From 3f2a162fab15aee243178b5308bb5d1206fc4043 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 6 Nov 2017 14:55:35 +0100 Subject: [PATCH] rtlwifi: fix uninitialized rtlhal->last_suspend_sec time We set rtlhal->last_suspend_sec to an uninitialized stack variable, but unfortunately gcc never warned about this, I only found it while working on another patch. I opened a gcc bug for this. Presumably the value of rtlhal->last_suspend_sec is not all that important, but it does get used, so we probably want the patch backported to stable kernels.
